ABSTRACT:
A rod guide molded in intimate contact with a sucker rod increases the amount of rod guide material available for wear. Adequate bypass area is provided so as not to impede the efficient movement of the rod and guide in tubing, yet more material for wear significantly lengthens the useful life of the rod guide. In a preferred embodiment, the rod comprises two guide elements, each with two lobes or vanes. The vanes of the two guide elements are opposed by ninety degrees for smooth operation and stability of the guide. Each lobe has an exterior contact surface with it circular radius of curvature that matches that of the tubing into which the guide is to be inserted.
